As the result of Test, all test compounds shown in Table 2 were provedto have antifungal activity.

TEST EXAMPLE 2 Test on treatment of trichophytosis

In the back of male Hartley guinea pig weighing 600 to 700 g, fourportions were unhaired in an area of 4 cm² respectively and rubbedlightly with sandpaper, to which the second generation of Trichophytonmentagrophytes incubated inversely from another guinea pig was infectedat 1×105 spores per portion. The test compounds obtained in Example 1was dissolved in ethanol and 0.2 ml of the resultant 0.1% solution wasapplied to the infected portions once in a day for ten days since 48hours after the infection. Test animal was killed 2 days after the lasttreatment and 10 tissue specimens from each infected portions wereplaced on Sabouraud's plates containing cycloheximide and kanamycin,which were incubated at 27° C. for 7 days. After incubation, existenceof fungi was observed and inhibitory ratio calculated according to thefollowing equation showed high value of 82%. ##EQU1##

TEST EXAMPLE 3 Side effect test

Two portions in the back of male Hartley guinea pig weighing 600 to 700g were unhaired in an area of 4 cm² respectively in order to examineside effects of the test compounds. The next day unhaired portions werelightly rubbed with sandpaper. The test compounds obtained in Example 1was dissolved in ethanol and 0.2 ml/day of the resultant 0.5% solutionwas applied to one of the unhaired portions, while 0.2 ml/day of onlyethanol was applied to the other portions, once in a day for ten daysrespectively.

As the result of test, side effects such as, for instance, erythema andpapula were not observed.
